在本篇中，我们将使用流通股份的集中程度作为指标，为大家开发如何机智的抢筹码策略！

股市里面总是有这样的一种说法：大股东总是会快小散一步，悄悄地进村，放枪的不要。大股东会在建仓期吸收世面上的廉价筹码，然后放出利好，逢高出货。所以大股东的建仓期，正是小散们入场分汤的好时机！

1. 数据准备

好了，说了这些原理，到底灵不灵呢？来，一试便知！这里我们首先要定义什么叫大股东呢？这里我们借助中诚信的数据，获取前十大流通股东的持股比例：

数据API： CCXE.EquMainshFCCXEGet 获取财报中十大流通股股东的持股比例（本API需要在数据商城购买）

下面的语句查询600000.XSHG浦发银行在2014年9月30日到2014年12月31日的十大流通股股东持股情况：

import datetime as dt
from CAL.PyCAL import *

data = DataAPI.CCXE.EquMainshFCCXEGet('600000.XSHG', endDateStart='20140930', endDateEnd='20141231')
data.head()

	secID	ticker	exchangeCD	secShortName	secShortNameEn	endDate	shNum	shRank	shName	holdVol	holdPct	shareCharType
0	600000.XSHG	600000	XSHG	浦发银行	NaN	2014-12-31 00:00:00	1	1	上海国际集团有限公司	3157513917	16.93	101
1	600000.XSHG	600000	XSHG	浦发银行	NaN	2014-12-31 00:00:00	2	2	上海国际信托有限公司	975923794	5.23	101
2	600000.XSHG	600000	XSHG	浦发银行	NaN	2014-12-31 00:00:00	3	3	上海国鑫投资发展有限公司	377101999	2.02	101
3	600000.XSHG	600000	XSHG	浦发银行	NaN	2014-12-31 00:00:00	4	4	百联集团有限公司	190083517	1.02	101
4	600000.XSHG	600000	XSHG	浦发银行	NaN	2014-12-31 00:00:00	5	5	雅戈尔集团股份有限公司	162000000	0.87	101

我们按照报表日进行合并，并计算前十大流通股股东持股总比例：

data.groupby('endDate').sum()

可以看到，2014年年报中流通股集中度是下降的，相对于上一个季报，持股总比例从29.76%降到了29.25%。看来他的大股东没啥动静，小散们先按兵不动！

2. 策略思路

有一句俗话：不要在一棵树上吊死！小散们可以“海选PK”，择优录取！我们以上证50成分股为例，挑选出满足以下条件的股票：

2015年一季度季报中10大流通股股东持股比例相对于去年年报上升10%

这就是我们认定的大股东吸筹码的标志：

from quartz.api import set_universe
import datetime as dt

universe = set_universe('SH50')

for stock in universe:
    try:
        data = DataAPI.CCXE.EquMainshFCCXEGet(stock, endDateStart='20141231', endDateEnd='20150331')
    except:
        continue
    res = data.groupby('endDate').sum()[-2:]
    if len(res.index) == 2 and res.index[1] == '2015-03-31 00:00:00':
        chg = res['holdPct'].values[1] / res['holdPct'].values[0] - 1.0
        if chg > 0.1:
            print '%s: %.4f' % (stock, chg)

选出来有三只股票满足：601169.XSHG, 600887.XSHG, 600703.XSHG

下面的股价走势图来看，这样的股票总体还是上升的。但是按照这样投钱真的靠谱吗？

import pandas as pd
stock1 = DataAPI.MktEqudAdjGet(secID=['601169.XSHG'], beginDate='20150331', endDate='20150429', field = ['closePrice', 'tradeDate'])
stock2 = DataAPI.MktEqudAdjGet(secID=['600887.XSHG'], beginDate='20150331', endDate='20150429', field = ['closePrice', 'tradeDate'])
stock3 = DataAPI.MktEqudAdjGet(secID=['600703.XSHG'], beginDate='20150331', endDate='20150429', field = ['closePrice', 'tradeDate'])

import seaborn as sns
sns.set_style('white')

total = pd.DataFrame({'601169.XSHG':stock1.closePrice.values, '600887.XSHG':stock2.closePrice.values, '600703.XSHG':stock3.closePrice.values})
total.index = stock1.tradeDate.apply(lambda x: dt.datetime.strptime(x, '%Y-%m-%d'))
total.plot(subplots=True, figsize=(12,8))

array([<matplotlib.axes.AxesSubplot object at 0x5543d10>,
       <matplotlib.axes.AxesSubplot object at 0x5572850>,
       <matplotlib.axes.AxesSubplot object at 0x56a62d0>], dtype=object)

3. 完整策略

我们来吧上面的想法系统化，来看这个策略效率：

投资域：上证50成分股
业绩基准：上证50指数
调仓频率：3个月
调仓日期：每年的2月28日，5月31日，8月30日，11月30日，遇到节假日的话向后顺延
开仓信号：十大流通股股东持股比例集中度上升10%
清仓信号：每个调仓日前一个工作日，清空当前仓位
买入方式：等比例买入
回测周期：2006年1月1日至2015年4月28日

这里的调仓日期的设置，是满足每期报表结束日后的两个月，这样我们有比较大的把握，可以确实拿到当前的报表数据。

import datetime as dt

            period = i
            break
        # 调仓日前一个交易日，清空所有的仓位
        elif today == cal.advanceDate(d, '-1B').toDateTime():

                order_to(stock,0)


    if rebalanceFlag:

        endDateEnd = str(year) + account.reportingPair[period][1]

            if len(res.index) == 2 and res.index[1] == str(year) + '-' + tmp[:2] + '-' + tmp[2:]+ ' 00:00:00':
                chg = res['holdPct'].values[1] / res['holdPct'].values[0] - 1.0
                if chg > 0.1:
                    buyList.append(stock)


        print u"%s 买入 : %s" % (today, buyList)

        # 等权重买入
        if len(buyList) != 0:
            singleCash = account.cash / len(buyList)
            for stock in buyList:
                approximationAmount = int(singleCash / hist[stock]['closePrice'][-1]/100.0) * 100
